Abstract: This invention provides an integrated process for converting a hydrocarbon feedstock having components boiling above about 100 °C into steam cracked products, which process comprises passing said feedstock to a hydrotreating zone at a pressure in the range of from about 400 psig to about 1,250 psig to effect substantially complete decomposition of organic sulfur and/or nitrogen compounds, passing the product from said hydrotreating zone to a steam cracking zone, and recovering therefrom hydrogen and C1-C4 hydrocarbons, steam cracked naphtha, steam cracked gas oil and steam cracked tar therefrom, wherein the amount of steam cracked tar produced is reduced by at least about 15 percent, basis the starting hydrocarbon feedstock which has not been subjected to hydrotreating.
Patent CA-2262886-A1 (CA)
Inventor: PONTE GARY W
IPC: A62C35/58
Filed: 1998-06-05
Abstract: In the typical sprinkler arrangements described in the specification, effective protection for certain special occupancy hazards is achieved with a low pressure water supply using VELO sprinklers (10) having a K factor of at least 14 (200 metric) arranged in arrays (76, 78, 80, 82) in which the sprinklers are spaced by ten feet (3 meters) in two orthogonal directions or by ten feet (3 meters) in one direction and by eight feet (2.4 meters) in an orthogonal direction. The commodities to be protected are stored in racks (60, 62, 64, 66) extending parallel to one of the orthogonal directions. For most hazards, a water pressure of 7 psi (0.5 bar ) is effective with sprinklers (10) having a K factor of 14 (200 metric). For plastic materials, a water pressure of 12 psi (0.8 bar) is effective for sprinklers having a K factor of 14 (200 metric) and, using sprinklers having a higher K factor, the pressure can be reduced to 7 psi (0.5 bar).

Title: System and method for measuring channel quality information in a communication system
Inventor: BALACHANDRAN KRISHNA
IPC: H04L1/12
Filed: 1999-02-26
Abstract: A system and method to measure channel quality in terms of signal to interference plus noise ratio for the transmission of coded signals over fading channels in a communication system. A Viterbi decoder metric for the Maximum Likelihood path is used as a channel quality measure for coherent and non-coherent transmission schemes. This Euclidean distance metric is filtered in order to smooth out short term variations. The filtered or averaged metric is a reliable channel quality measure which remains consistent across different coded modulation schemes speeds. The filtered metric is mapped to the signal to interference plus noise ratio per symbol using a threshold based scheme. Use of this implicit signal to interference plus noise ratio estimate is used for the mobile assisted handoff in a cellular system, power control and data rate adaptation in the transmitter.

Abstract: Procédés permettant de purifier des enzymes, notamment des acylases, caractérisés par le fait que l'on agrège et précipite sélectivement les enzymes contaminantes, notamment les désacétylases, au moyen d'agents tensioactifs, notamment de tensioactifs cationiques; procédés permettant de régénérer les supports d'enzymes immobilisées, notamment ceux constitués d'absorbants synthétiques ou de résines échangeuses d'ions, en traitant les enzymes immobilisées, que l'on prépare en fixant les enzymes sur les supports, puis éventuellement en les réticulant avec des protéases; procédés permettant de régénérer les supports décrits ci-dessus, lesdits supports étant poreux; et procédés permettant de régénérer les supports décrits ci-dessus, l'enzyme étant une céphalosporine C acylase. Les procédés de purification d'enzymes décrits ci-dessus permettent d'éliminer sélectivement les enzymes contaminantes qui sont indésirables pour les enzymes cibles, mais qui ne peuvent pas être éliminées par les techniques de séparation classiques. Ces procédés sont donc utiles pour produire des échantillons d'enzymes extrêmement pures. Par comparaison avec les procédés classiques, les procédés de régénération des supports d'enzymes immobilisées décrits ci-dessus permettent d'éliminer très efficacement les enzymes des supports, notamment poreux, par digestion avec des protéases. Les supports peuvent ainsi être utilisés de manière répétée, ce qui rend ces procédés intéressants du point de vue de l'environnement et du coût.

Title: Engineering plant thioesterases and disclosure of plant thioesterases having novel substrate specificity
Inventor: YUAN LING
IPC: C12N15/29
Filed: 1998-06-03
Abstract: Methods of altering substrate specificity of plant acyl-ACP thioesterases, and engineered plant acyl-ACP thioesterases so produced are provided. The C-terminal two thirds portion of plant thioesterases is identified as desirable for such modifications. DNA sequences and constructs for expression of engineered thioesterases, as well as the novel thioesterases produced therefrom are also provided. Such DNA sequences may be used for expression of the engineered thioesterases in host cells, particularly seed cells of oilseed crop plants, for the modification of fatty acid composition. A C12 preferring plant acyl-ACP thioesterase described herein may be altered to obtain a plant thioesterase having approximately equal activity on C14 and C12 substrates.  Further modification of the C12 enzyme yields a thioesterase having greater activity on C14 as compared to C12 substrates. Of particular interest is a plant 18:1 thioesterase in which the relative 18:0 activity has been increased. Such FatA thioesterases find use for improved production of stearate in vegetable seed oils.
